As you go down a group on the periodic table, atomic radii tend to increase because elements with larger atomic numbers have more occupied electron levels which take up more space surrounding the nucleus.

I hope this helps.

How is it possible for two neutral objects to become charged by rubbing them together? A. The binding force of the objects’ atom
FinnZ [79.3K]

Answer:

D. The frictional force overcomes the force that binds the electrons to the atoms, enabling the electrons to move elsewhere

Explanation:

Neutral objects becomes charged by rubbing them together due to the frictional force which overcomes the attractive force holding electrons together in an atom.

Friction is the resistance to flow or movement. When we rub bodies together, the movement of electrons becomes inhibited and this can cause an orbital electron loosely held in an atom to be pulled off as the force of friction increases. This mechanism would result in a body losing electron and another readily gaining that electron as they interact. The loss and gain of electrons causes a neutral body to become charged.

Goshia [24]
The  atomic  number  of  calculated as  number  of  protons  +  number  of  neutrons. The  number  of  protons  are  the  same  as  atomic  number.  This  implies  that  Nitrogen  has  seven  protons.  To  get  the  the  number  of  neutron  we minus  atomic  mass  from  number  of  protons
     that  is  14-7=7  neutrons
